Dietmar Schomburg,Ida Schomburg first impossible differential, differential and linear cryptanalyses of MIBS. Their best attack was a linear attack on the 18-round MIBS-80. In this paper, we significantly improve their attack by discovering more approximations and mounting Hermelin et al.’s multidimensional linear cryptanalysis.

In this paper, we complete their observation by showing SPRP-insecurity even if we have linear mixing over any non-binary prime field. We have some positive result that P

Dietmar Schomburg,Ida SchomburgWe also use Nguyen et al.’s technique to have less time complexity. We attack on 19 rounds of MIBS-80 with a time complexity of 2. 19-round MIBS-80 encryptions by using 2. plaintext-ciphertext pairs. To the best of our knowledge, the result proposed in this paper is the best cryptanalytic result for MIBS, so far.
